From 41ea82c88cb666ee600df9ef8fafec4cea3432c0 Mon Sep 17 00:00:00 2001 From: Paul Eggert Date: Tue, 27 Dec 2022 08:15:37 -0800 Subject: Make autogen a shell function too MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This does not change behavior. It is helpful for future changes. * top/autogen.sh: Call autogen to do the actual work. (usage, version_controlled_file, gitignore_entries, insert_if_absent): (insert_vc_ignore, symlink_to_dir): Move to top/bootstrap-funclib.sh. * top/bootstrap-funclib.sh (autogen_usage): Rename from ‘usage’. (autogen): New function, containing the top level of the old top/autogen.sh. --- top/autogen.sh | 449 +--------------------------------------------- top/bootstrap-funclib.sh | 451 ++++++++++++++++++++++++++++++++++++++++++++++- 2 files changed, 451 insertions(+), 449 deletions(-) (limited to 'top') diff --git a/top/autogen.sh b/top/autogen.sh index 4ca4c05577..1cb918640d 100755 --- a/top/autogen.sh +++ b/top/autogen.sh @@ -4,8 +4,6 @@ # also regenerates all aclocal.m4, config.h.in, Makefile.in, configure files # with new versions of autoconf or automake. -scriptversion=2022-12-27.03; # UTC - # Copyright (C) 2003-2022 Free Software Foundation, Inc. # # This program is free software: you can redistribute it and/or modify @@ -38,449 +36,4 @@ medir=`dirname "$me"` # Read the function library and the configuration. .
